In order to prevent the serious erosion of the Yangtze River bed,resulting in bank slope instability or collapse,the concrete hinge row construction technology is used for protection.The technology is to prefabricate reinforced concrete slabs firstly,and then use the'U'ring to connect the concrete slabs.Through the sinking row ship and related equipment,the row body is sunk to the protective position specified in the design.The divers explore the row body,underwater measurement,underwater camera and other means to check the overlap and sinking quality of the row body.The application results show that after years of operation and monitoring,the river bed is stable,the revetment effect is good,the revetment structure is stable and reliable,and there is no obvious erosion and collapse in the area protected by concrete hinge row.The concrete hinge row sinking technology plays an important role in resisting the erosion and erosion of water flow in the Yangtze River revetment project,and provides reference for similar projects.
